What?

The inline documentation for the function setGroupingBlockName had incorrect helper text. This update the button text in the Example Component to indicate what passing core/columns to setGroupingBlockName would actually do.

Why?

The current documentation for this function is confusing since it was probably pulled from the documentation of a different function.

How?

This updates the wording and adds a bit more explainer text to make this easier to understand.

Here's the change:

Assigns name of block for handling block grouping interactions.

This function lets you select a different block to group other blocks in instead of the
default core/group block. This function must be used in a component or when the DOM is fully
loaded. See https://developer.wordpress.org/block-editor/reference-guides/packages/packages-dom-ready/

@param {string} name Block name.

@example

import { setGroupingBlockName } from '@wordpress/blocks';

const ExampleComponent = () => {

    return (
        <Button onClick={ () => setGroupingBlockName( 'core/columns' ) }>
            { __( 'Wrap in columns' ) }
        </Button>
    );
};
